Application filed May 18, 1912. Serial No. 698,329.

T 0 all whom it may concern 'Be it known that we, Jncos J noon R.vHessiansin-21X, citizens or BLE'NZ and the United States, residing atDecatur, in the j county of Macon and State of ll. mois, have inventedcertain new and useful Improvements in Refrigerating Apparatus, of whichthe following a specification. reference being had to the accompanyingdrawings.

This invention relates to improvements in refrigerating apparatus andhas tor its object to provide means whereby a constantlj',

circulating current of cold air may be. sup-- plied to the provisionchamber froma minimum quantit of ce or other refrigerant, thus inaternly reduclng the expense incident to the operation of apparatus of thischaracter.

Another ob ect of the invention 1s to pro.- videan ice box provided with311311 receiving chamber, means arranged in the box beneath said icetoreceive the air, and a fan having a pipe connecting the same with theair chamber, said tan directing the tar into and throughsaid recelvlngmeans. in

' the icebox to a supply pipe connecting the air chamber with theprovision chamber of the refrigerator.

Still another object of the invention re sides in the provision of abrine containing tank and a pipe connecting the same to the air ch mberof the ice box, and a pipe connected at one of its ends tot-he bottom ofthe provision chamber and at its other endto said first named pipe toreturn the air from the provision. chamber to the cold air chamber ofthe ice box.

. A. still further object of the invention is to provide an apparatusfor the above purpose which is comparatively simple in its. co

struction, may be manufactured and installed. at small cost and ishighlyefficient and reliable in practical'use. I v.

With the above and other objects in view as Wlll become apparentas thedescription proceeds, the invention consists in certain constructions,combinations and arrange ments of the parts that wev shall hereinafterfully describe and claim.

"For a full understanding f. the invention, referencev is to be had tothe following description and accompanying drawings, in

whichl is an elevation, the Walls of the refrigerator being shown. insection; Fig; 2

Corresponding and like parts are referred to in the followingdescription and laccompanying drawlngs by like reference characters.

partments. The lower compartment of the refrigerator is furnished withthe usual hooks, hangers and other accessories upon which meats andother, provlslons are arranged. In the upper chamber 5 an ice box a 7 isarranged. This icebox is'. preferably of rectangular form and on threesides is provided with inner and outer walls 8 and 9 respectively, toprovide an air receivingchamber 10 between them, These walls may beconstructed inany desired manner, and.

provided with a heat insulating medium.

The other wall 11 closes the .airreceiving chamberlO at one of its ends.r

/Vithinthe ice box-7; and uponthe bottom thereof the air receivingmember 124s ar- I ranged. This member consists'of-spaced ransverse pipes13 and a plurality of longitudinal pipes 14 which connect the trans--verse pipes. Ulpon these pipesthe-supply of ice within the chest isarranged.= One of the pipes 13 is provided with a 'centralre ducedlaterally extending nipple .15, to

which a pipe 16 extending from the-fan case 17 is connectedfih enipple'lo-e'xtera ling,1

through the endwalls 11- of the'ice box' adjacent'to itsll'ower end-.1J'A fan'18 is. arranged in-the casing 17 and the fan 'shaft is providedon one end with a band'wheel to shaft of a motor'is connected. A pipe 19is also connected tothe fan case at one of it's' ends, the other end. ofsaid pipe being extended through the end. r all 111. of the ice box intotheair chamber thereof.

Through the other end of the icebox' a pipe partition wall G'andbeingprovided upon which a driving belt "extending from thee ing centrallyfrom the other .of the transverse pipes 13 of the air receiving member12. "By means ot'wthis arrangement'of -parts ii t' itwill be readilyunderstood that the air is ,drawn.-into' the. fan case from the chamthechamber, of the ice box.

ber 10 through the pipe 19 and driven into .the' end pipe 13 of the{member 12 and through the longitudinal pipe-e 14 into the other endpipe 13 vfrom which it is exhaust ed through thepipe '20 into theprovision chamber of the refrigerator.

The-chamber 10 of the ice box is constantly supplied with air from abrine tank -'23- -:-wh ich is arranged at any convenient po nt nfltheprovlsionchamber and is c0nnected to said chamber by means of the pipe24, the walls of. the tank 23-being provided with suitable. air inletopenings; shown at"v 23. A d-raln pipe .25 extending from thebottom ofthe ice box 7 carries .the water from the melting ice, to the upper endof the brine tank 23. Thiswater percolating through the brine in thetank generates a vapor'which rises through the pipe 24 and enters thechamber 10 of theice chestr A pipe 26 is arranged in the tank 23 andextends to the surface of the brine therein to receive the overflow, thelower end of the plpe extending exterio'rly of the tank to discharge thewater and brine.- To the pipe neath the ice in the manner above stated.It will thus be apparent that a constantly circulating current of coldair is maintained through the provision chamber of the] refrigerator.

- The expense incidentto the consumption of ice is materially reduced bymeans of our improved apparatus and even when the ice. supply has becomeentirely exhausted, the

cold air rising from the brine tank and be ing driven by the fan throughthe ice box will still maintain the provision chamber at a lowtemperature.

From the foregoing 1t is'believed that the construction and manner ofoperatlon of our improved refrigerating apparatus will be clearlyunderstood, The device is extremely eificient, and reliable inlactualuse and owing to the sim plicity ofits construction, the same may. be

readily installed in the ordinary refrigerator at comparatively smallcost.

While-gwefhave above set forth the preferred construction andarrangement of the various parts employed, it will be obviousthat theinvention is susceptible of considerable modification without departingfrom the, essential features or sacrificing any of the advantagesthereof.

Having thus described the invention what is claimed is:

1 I-;'-- In a refrigerating apparatus, an ice- "chest having an airchamber, an an re .ceiving g'r1d'- arranged 1n sald chest and providedwith an inlet for the cold air at one of its ends, a discharge pipeconnected to the other end of the gridto receive, the

airtherefrom'and discharge the same into the provision chamber of therefrigerator,

chamber, an air conducting pipe connected to the brine tank and to theair chamber tr supply air to the latter, and an air return pipeconnectedto saidlast referred-to pipe and extending into the provisionchamber to a point adjacent the bottom thereof.

a brine tank arranged in the provision 2. In a refrigeratingapparatus,an ice chest provided with an air chamber, an air receiving gridarranged in said ice chest" upon which the ice 1s supportedfa fanconnected 'to said grid, a pipe connecting the fan case to the airchamber of the ice-chest, a brine tank, a drain pipe connected to saidtank and .to the ice'chest, an air conducting pipe connected to the tankand to the an.

chamber of the chest, a discharge pipe con- 'nectedto the grid todischarge the cold-air therefrom into the, provision chamber of therefrigerator, and a pipe connected to the provision chamber and to" thepipe connection between thebrine tank and the chamber of the "ice chestto return the com-paratively warm airfronrthe provision, chamber to thechest chamber.
